Feminist author Germaine Greer today stood by comments she made criticizing Caitlyn Jenner and transgender women following a wave of criticism this weekend. Greer, whose best-selling 1970 book The Female Eunuch focused on the ways in which women’s bodies and sexuality are repressed by society, told the British show VictoriaLIVE today that she understands that “some people are born intersex and they deserve support in coming to terms with their gender but it’s not the same thing. A man who gets his d**k chopped off is actually inflicting an extraordinary act of violence on himself.”

Greer was the subject of a Change.org petition by students at Cardiff University in England demanding that her appearance on campus be canceled because she had previously made offensive comments about transgender women. The university refused to cancel the appearance but Greer announced this weekend she will no longer attend. She then went on the BBC2 show Newsnight Friday and took aim at Jenner, criticizing Glamour magazine for reportedly considering Jenner for its Woman of the Year Award.

“I think misogyny plays a really big part in all of this, that a man who goes to these lengths to become a woman will be a better woman than someone who is just born a woman,” Greer said.

Greer is still regarded as a leading voice of second-wave feminism, and the backlash over her comments has exposed a rift in thinking between the author and a younger generation of feminists and LGBT supporters over the importance of the body in gender identity.
